| Abstract: | Multi-beam bathymetric technology represents an efficient means for measuring underwater terrain, furnishing more detailed depth information compared to single-beam bathymetry. However, optimizing the deployment of survey lines to achieve high efficiency and precision remains a crucial challenge. This paper endeavors to optimize the surveying process by formulating mathematical models and optimization algorithms for the coverage width and overlap rate in multi-beam bathymetry, with the aim of minimizing the length of survey lines. The research is carried out in three consecutive stages. In the initial stage, a mathematical model for the multi-beam coverage width and overlap rate is constructed, leveraging the geometric relationships inherent in an ideal sloping seafloor. Subsequently, the model is enhanced by permitting the horizontal projection angle between the survey line direction and the seabed slope normal to be arbitrary. The coverage width model is further refined through the clarification of geometric relationships. Finally, in the case of complex seafloor terrains, the entire sea area is partitioned into several survey zones, each of which is approximated as a regular sloped plane, to develop a single-objective optimization model for the exploration of survey line deployment. By solving the models with MATLAB, computed results for water depth, coverage width, and overlap rate under diverse conditions are obtained, and the survey line deployment plan is visualized. This study successfully constructs an optimization model for multi-beam bathymetry and validates its effectiveness through examples, providing a theoretical foundation and practical guidance for actual marine surveying, thereby contributing to the improvement of the efficiency and accuracy of marine mapping.
